Harness
The six-layer harness scorecard and trip wires, plus the diagrams that illustrate how the hub's loops run across the fleet.

🧬 Harness
Agent = Model + Harness. The model reasons; everything else — guides, sensors, bounded loops, memory, permissions, observability — is this repo. The scorecard and trip wires below are computed offline from the committed fleet signals by dash-gen harness (refreshed daily by fleet-pulse.yml) into _data/harness_health.yml. Thresholds live in _data/fleet.yml → harness:. Operator guide: docs/HARNESS.md.

Trip wires
A tripped wire is an attention item, not an action — the doctor, issue pipeline, and rotation loops own the fixes. Every wire is listed, armed or tripped, so a quiet panel is distinguishable from a lost one.
| Wire | State | |
|---|---|---|
| armed | stale-data |
all fleet signals fresh |
| armed | pass-rate-floor |
fleet workflow success rate 89.7% vs floor 75% |
| TRIPPED | waste-ceiling |
wasted minutes 51.7% of total vs ceiling 30% |
| TRIPPED | cost-spike |
workflows averaging ≥3.0× the fleet median (0.83 min)
|
| armed | standing-failures |
28 standing red workflows vs max 30 |
| TRIPPED | credential-overdue |
a fleet credential is past its rotation policy plus grace
